The Knoll-Campbell Family of Western Pennsylvania

I am researching the KNOLL-CAMPBELL family from Edinburg and New Castle, Lawrence County, Pennsylvania. My Grandfather Joseph Frederick KNOLL was born in Harlansburg, Lawrence County, PA, in Feb.1861. He married Laura Belle CAMPBELL, born Apr. 1866 in New Castle, Lawrence County, PA. They eventually had three daughters, Edith, Mary and Elizabeth. They also had four sons, Fred, Newton, John and Joseph Francis. Laura Belle and Joseph Frederick resided on the KNOLL family farm in Edinburg until their death during the 1940's.Any information you have about these families would be sincerely appreciated, Of course, I'm very willing to share any information I have
